干式变压器线圈内部放电的探测至关重要,一旦探测放电位置来自线圈内部,如匝间、饼间、段间、层间等位置,线圈就须报废处理,否则将影响产品的使用寿命.介绍了极性辨别法在干式变压器局部放电测量中的应用,该方法运用了脉冲信号向线圈两端传播的特性,通过信号极性来判定线圈内部是否存在放电点.
Application of Polarity Discrimination Method in Partial Discharge Detection of Dry-type transformers
The detection of internal discharge of dry-type transformers coils is of great importance.Once the detected dis-charge position locates inside the coil,e.g.,positions of inter-turn,inter-round,inter-section,inter-layer,it will affect the service life of the product and the coil should be scrapped.This paper outlines the application of polarity discrimination method in detecting partial discharge of dry-type transformers,which uses the characteristics of pulse signal propagation to both ends of the coil to determine whether there are discharge points by signal polarity.
